Bidders must demonstrate commitment to 17% women and minority-owned business enterprise (WMBE) utilization and submit an Inclusion Plan with a minimum score of 10 points across three commitment options: Aspirational WMBE Goals (up to 6 points), Business Support Strategies (up to 4 points), and WMBE Guarantees (up to 6 points). Projects estimated over $1 million require a Bidder/Subcontractor List identifying subcontractors for rebar installation and electrical work, or indicating intent to self-perform. All bids are subject to prevailing wage requirements under RCW 39.12, paid sick and safe time compliance per SMC 14.16 and RCW 49.46, and EPA Consent Decree stormwater and sanitary sewer compliance.

The scope includes rebar installation and electrical work as identified subcontractor items. The Engineer's Estimate is $2.5 million to $2.7 million. The contractor must physically complete all work within 100 working days from Notice to Proceed; liquidated damages apply for delays beyond that deadline. Bidders must submit a bid guaranty of not less than 5% of the total bid amount including retail sales tax at 10.55%. Bidders must also propose the percentage of recycled construction aggregate and concrete materials, which serves as a tiebreaker if bid totals are equal.

No pre-bid site inspection meeting is scheduled.
